Architecture of a single-page JavaScript web application?

Question

How should a complex single-page JS web application be structured on the client-side? Specifically I\'m curious about how to cleanly structure the application in terms of it

Answer 1

The way I build apps:

• ExtJS framework, single page app, every component defined in a separate JS file, loaded on-demand
• Every component contacts its own dedicated web service (sometimes more than one), fetching data into ExtJS stores or special-purpose data structures
• The rendering uses standard ExtJS components, so I can bind stores to grids, load forms from records, ...

Just choose a javascript framework, and follow its best practices. My favorites are ExtJS and GWT, but YMMV.

Do NOT roll your own solution for this. The effort required to duplicate what modern javascript frameworks do is too big. It is always faster to adapt something existing than to build it all from scratch.
